Creepiest Unsolved Mysteries Of All Time – The Atlas Vampire
In 1932, a 32-year-old Swedish prostitute named Lily was found dead in her apartment. She had been dead for three days or so when the police broke into her apartment. The scene was grizzly, but it got really weird when they realized that her body had been drained of almost all of its blood. A gravy ladle was found near her body, which police believed was used to drink the drained blood. No one was ever convicted of the murder.
